Biology 1001 2 Part Discussion – 20210621K

*** There are 2 parts to this. **** Part One: Due Tuesday, 06/22/2021 Choose one of the following questions to answer – 2 paragraphs 1) Connect your study of genetics last week to human evolution this week by conducting independent research into human chromosome #2. Explain how chromosome numbers in human presented a testable challenge to our understanding of Homo sapiens descent from a common primate ancestor. Be sure to explain how this challenge was tested and what we found. Here are some good sources for this: http://www.youtube.com/watch?v=8FGYzZOZxMw http://www.pbs.org/wgbh/evolution/library/07/3/l_073_47.html 2) Describe and explain how scientists are using genetics to trace the relationships between different human populations and migrations via the Genographic Project. https://www.youtube.com/watch?v=RGtaq3PiIoU https://reimaginingmigration.org/teaching-with-nat…

This is a partial list of some of the poplar misconceptions about evolution: Misconceptions about evolutionary theory and processes Misconceptions about natural selection and adaptation Misconceptions about evolution and the nature of science Misconceptions about the acceptance of evolution http://www.nhm.ac.uk/discover/the-origin-of-our-species.html Part 2: Due Thursday, 06/24/2021 Post two or more paragraphs evaluating the significance of your selected mutation’s role in human evolution. Your evaluation should include the following: Requirements: As directed above Evolution is a theory about the origin of life. Evolutionary theory implies that life evolved (and continues to evolve) randomly, or by chance. Evolution results in progress; organisms are always getting better through evolution. Individual organisms can evolve during a single lifespan. Evolution only occurs slowly and gradually. Because evolution is slow, humans cannot influence it. Genetic drift only occurs in small populations. Humans are not currently evolving. Species are distinct natural entities, with a clear definition, that can be easily recognized by anyone. Natural selection involves organisms trying to adapt. Natural selection gives organisms what they need. Humans can’t negatively impact ecosystems, because species will just evolve what they need to survive. Natural selection acts for the good of the species. The fittest organisms in a population are those that are strongest, healthiest, fastest, and/or largest. Natural selection is about survival of the very fittest individuals in a population. Natural selection produces organisms perfectly suited to their environments. Evolution is not science because it is not observable or testable. Evolution is ‘just’ a theory. Evolutionary theory is invalid because it is incomplete and cannot give a total
explanation for the biodiversity we see around us. Gaps in the fossil record disprove evolution. The theory of evolution is flawed, but scientists won’t admit it. Evolution is a theory in crisis and is collapsing as scientists lose confidence in it. Most biologists have rejected ‘Darwinism’ and no longer agree with the ideas put forth by Darwin and Wallace. A brief description of the mutation A brief explanation of when and how the mutation occurred At least two ways in which the human population benefited from the mutation Your position on the significance of this mutation in human evolution Reference to at least two sources outside the Required Resources All references cited in APA format
